These surface mining methods are considered to be more efficient and economical in extracting minerals as compared to most methods of underground mining. In fact, it can extract almost 90% of ore from a deposit. For this reason, surface mining is the most widely used method in North America.
Open-pit and area mines are associated with extraction of thick deposits. These justify mining of deeper overburden/cover rock. They are typically multiple bench type operations with special consideration required for the vertical lift requirement...
Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, and social factors.
Surface Mining Methods and Equipment - eolss - CIVIL ENGINEERING Vol. II - Surface Mining Methods and Equipment - J. Yamatomi and S. Okubo is essentially surface-based. Surface mining can be classified into two groups on the basis of the method of extraction; mechanical extraction, or aqueous extraction.
In all methods of surface mining, first, the overburden is stripped off using earthmovers.Then, bucket-wheel excavators remove the ore, which is loaded into haul trucks with shovel loaders. When the deposit is exhausted, the overburden is refilled in the crater, and the land is restored with the local vegetation.
continuous mining survey in pakistan. Most bauxite iron and copper ore is mined by open pit techniques lead and zinc ore are principally extracted by underground mining methods and precious metals particularly gold and most notably in the USA and Australia tend to be recovered in recent years
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
It is an advantageous mining method f or shallow orebodies – as a means of preventing surface subsidence. Historic, ultra-shallow under ground coal mines (< 30 m) nevertheless are
